Based on the embodiments of the present invention, all other embodiments obtained by a person of ordinary skill in the art without creative efforts belong to the protection scope of the present invention.

Example 1

An automatic ash discharging device with an adjusting mechanism for an industrial boiler comprises an ash discharging hopper 1, a motor 2, a fixing plate 8, a rotating column 7 and a screen 12;

the top of the ash bucket 1 is connected with an ash inlet nozzle 11, a first round hole 801 is symmetrically arranged in the fixed plate 8, and the lower end of the fixed plate 8 is attached to the upper end of the rotating column 7; a second round hole 701 is arranged in the rotating column 7 corresponding to the first round hole 801, a circular convex strip 702 is arranged on the rotating column 7, a circular groove 102 is arranged on the inner wall of the ash bucket 1 corresponding to the circular convex strip 702, and the circular convex strip 702 is rotatably connected with the circular groove 102;

the middle part of the bottom end of the rotating column 7 is connected with a second rotating shaft 6, a second type bevel gear 5 is arranged on the second rotating shaft 6, the left end of the second type bevel gear 5 is meshed with a first type bevel gear 4, and the first type bevel gear 4 is arranged on the first rotating shaft 3; a fixed sleeve 14 is fixed on the first rotating shaft 3, and the lower end of the fixed sleeve 14 is connected with a steel ball 16 through a connecting rod 15; the first rotating shaft 3 extends out of the ash bucket 1 leftwards and is connected with the motor 2, and the motor 2 is connected to the outer wall of the left side of the ash bucket 1; the two ends of the screen 12 are connected with the inner wall of the ash bucket 1, the ash discharge pipe 13 is arranged at the ash bucket 1 corresponding to the left end of the screen 12, and the bottom end of the ash bucket 1 is connected with an ash discharge port 101.

The first round hole 801 and the second round hole 701 have the same aperture, so that ash falls down from the first round hole 801 and the second round hole 701 conveniently.

The middle part of the bottom end of the ash inlet nozzle 11 is connected with a partition plate 10, and the bottom end of the partition plate 10 is connected with a fixed plate 8; fixed plate 8 with put 1 inner wall fixed connection of ash bucket, 8 upper ends bilateral symmetry of fixed plate is connected with baffle 9, and baffle 9 tops with put 1 inner wall connection of ash bucket, baffle 9 is the funnel shape, the lime-ash of being convenient for is followed and is put 1 interior all outflows of ash bucket.

The partition plate 10 is conical, so that ash can uniformly enter the ash bucket 1 of the partition plate 10, and the ash can conveniently fall onto the screen 12 from the first round hole 801 and the second round hole 701.

The first round hole 801 is correspondingly arranged between the partition plate 10 and the bottom end of the baffle plate 9, so that ash residue cannot remain in the ash bucket 1.

The connecting direction of the screen 12 is left low and right high, which is convenient for the screen 12 to effectively screen different components of the ash slag.

The working mode of the automatic ash discharging device with the adjusting mechanism for the industrial boiler is as follows: boiler ash enters the ash bucket 1 from the ash inlet nozzle 11, the ash passes through the partition plate 10 and is uniformly distributed to two sides of the partition plate 10, and the baffle plate 9 prevents the ash from staying on the fixed plate 8, so that the ash can be discharged; motor 2 takes to time to separate to rotate, motor 2 drives axis of rotation 3 and rotates, a kind of bevel gear 4 and two kinds of bevel gear 5 meshes, two kinds of bevel gear 5 rotate along with a kind of bevel gear 4 and rotate, two kinds of bevel gear 5 rotate and drive No. two axis of rotation 6 and rotate, No. two axis of rotation 6 drive the rotation post 7 and carry out the rotation work, owing to put ash bucket 1 and be equipped with circular recess, circular sand grip 702 rotates with circular recess and is connected, the rotation post 7 carries out the interval rotation, when No. two round holes 701 and a round hole 801 contactless, the device stores the work to the lime-ash.

When the second round hole 701 and the first round hole 801 are contacted with each other, ash begins to fall in the first round hole 801 and the second round hole 701; when the centers of the circle of the second round hole 701 and the circle of the first round hole 801 are coaxial, the falling amount of ash slag is maximum; on ash and slag whereabouts to screen cloth 12, because a axis of rotation 3 drives fixed cover 14 and rotates, connecting rod 15 rotates along with fixed cover 14, can touch screen cloth 12 when steel ball 16 rotates, because screen cloth 12 self has elasticity, screen cloth 12 can shake, and then accelerates the speed that the ash and slag was sieved, improves the work efficiency who puts the ash.

Finally, ash slag screened off from the screen 12 is discharged from the ash discharge port 101 into one ash storage tank, the ash slag which cannot be screened off falls to the ash discharge pipe 13 through the screen 12 towards the left and downwards, the ash slag is discharged from the ash discharge pipe 13 into another ash storage tank, and workers perform corresponding treatment on different ash slag.

The motor, bevel gear, the screen cloth that this patent adopted are the market, and its structure and control mode are prior art, no longer give unnecessary details in the description.
